Answer:
It will be 4 hours until the temperatures are the same
Step-by-step explanation:
Let 
represent the temperature in Coldspot in 
hours and
represent the temperature in Frostberg in hours.
From the question,
The temperature in Coldspot is -7° and is increasing 2.5° per hour, then we can write that
Also, from the question,
The temperature in Frostberg is 19° and is decreasing 4° per hour, then we can write that
To determine how long it will be until the temperatures are the same, that is when will be equal to , we will equate the two equations and determine .
will give the number of hours until the temperatures are the same.
Then,
∴ 
Hence, it will be 4 hours until the temperatures are the same.

Answer:
A2 = 120
A3 = 60
A5 = 60
A6 = 120
Step-by-step explanation:
Angle 1 and 2 are supplementary, so A2 = 180 - 60, which is 120.
Angle 1 and 3 are vertical angles, which are always the same measure.
Angle 5 is alternate interior angles with 3, which means it is also 60.
Angle 6 is alternate interior angles with 4, which means it is 120.
